Types of ERP Systems: Choosing the Right Solution for Your Business

Enterprise Resource Planning or ERP are software solutions that are a centralized hub for managing an array of essential business functions. These encompass everything from accounting and procurement to project management, risk management, compliance, human resources management and supply chain operations.  ERP systems connect and synchronize the different business processes, enabling consolidation of transactional data from diverse sources.

What is an ERP System?

Enterprise Resource Planning (ERP) systems are comprehensive business process management software tools that centralize applications, and streamline operations like accounting, human resources, and sales. By facilitating the flow of data between these applications, ERP systems enhance efficiency, profitability, and time savings for organizations across diverse sizes and industries. 

The evolution of ERP may be traced to inventory management in the 1960s during which industries recognized the necessity for systems to manage and control inventory, leading to the inception of Material Requirements Planning (MRP) in the 1970s. MRP evolved to address manufacturing needs, utilizing software applications for scheduling production processes based on production requirements, system structures, and inventory levels.

In the 1980s, Manufacturing Resource Planning (MRP II) emerged, integrating additional manufacturing processes for enhanced accuracy and efficiency. The 1990s witnessed the birth of ERP, a term coined by The Gartner Group, ushering in multi-module application software to optimize internal business processes across various departments. Despite initial adoption challenges for small and medium-scale businesses, the 2000s saw ERP II, facilitating interaction with other application suites and adapting to technological advancements.

The 2010s witnessed the rise of Cloud-based ERP, delivering software as a service (SaaS) with minimal upfront costs, making ERP accessible to businesses of all scales. Simultaneously, open-source ERP solutions evolved, catering to the needs of budget-conscious small and medium-scale enterprises. This dynamic evolution reflects the continual adaptation of ERP to technological advancements, accessibility demands, and the diverse requirements of businesses across different scales.

Why do you need an ERP system?

As businesses expand, the escalating workload for administrators necessitates a shift from manual methods like spreadsheets and email towards more robust solutions. The introduction of Enterprise Resource Planning (ERP) software becomes pivotal in seamlessly integrating diverse activities within a single application. This integration not only streamlines processes but also enhances agility, ensuring businesses can effectively meet growing customer demands during crucial growth phases.

Here are five compelling reasons why investing in ERP software is imperative for businesses:

1. Software standardization: ERP systems unify disparate applications, mitigating data transfer chaos, reducing time-consuming processes, and enhancing security. A centralized dashboard, access control features, and increased data security streamline operations, offering a cohesive user experience.
2. Efficient Accounting: As companies grow, managing financial complexities becomes paramount. ERP applications automate transaction tracking, eliminating the need for repetitive data entry. This centralized platform enhances visibility into crucial operational data, contributing to better financial management.
3. Faster Response Times: Improved service delivery and customer service differentiation hinge on integrated systems. ERP software ensures front-line executives and sales teams have maximum access to information across departments, contributing to faster response times and better customer service.
4. Compliance to regulations and security features Integrated ERP software aids in aligning back-office operations with industry regulations. ERP solutions monitor compliance changes and enhance security through features like regulated data access and built-in firewall systems.
5. Adaptability: Modern workplace trends, such as Bring Your Own Device (BYOD), demand flexibility in enterprise software. ERP solutions, leveraging centralized databases, provide accurate information globally, on any device. This flexibility ensures efficient remote access, saving time and effort while meeting quality work standards.

Types of ERP Systems

ERP Systems are of various types depending on the business needs. The classification of ERP types is based on several characteristics.  Some classifications of ERP systems are:

Custom-built, Ready-made, or Hybrid Solutions:

• Custom ERP: Tailored to precise business requirements, custom ERPs are developed by specialized companies. This approach ensures alignment with unique processes and needs.
• Ready-made ERP: Also known as off-the-shelf solutions, these are pre-built software packages. Examples include Microsoft Dynamics, SAP Business One, Acumatica ERP, and Oracle EBS.
• Hybrid ERP: Blending existing ERP solutions with new modules or custom features, hybrid models provide flexibility and customization within a familiar framework.

Cloud-based or On-premises ERPs

• Cloud-based ERPs: Hosted on vendor servers and accessed over the internet, cloud ERPs offer cost-effective solutions, especially for small businesses. Examples include Oracle Netsuite, Microsoft Azure, Infor CloudSuite, and Acumatica Cloud ERP.
• On-premises ERPs: Installed on an organization's computers and servers, on-premises ERPs provide full control over the system but require significant upfront investment. SAP ERP, SYSPRO ERP, and Microsoft Dynamics GP are notable examples.
• Hybrid ERP: Some vendors offer a hybrid ERP option, combining on-premises software with private or public cloud elements for storage, services, or computing.

Generic or Industry-specific ERPs

• Generic ERPs: Providing broad functionality across multiple industries, generic systems excel in financial management and accounting but may lack industry-specific features. Examples include Epicor ERP, Infor ERP, and SAP Business One.
• Industry-specific ERPs: Tailored to niche industries like manufacturing, distribution, or professional services, these systems offer specialized features essential for their respective sectors. Microsoft Dynamics, Infor CloudSuite, and QAD are popular in manufacturing, while Oracle NetSuite and Microsoft Dynamics serve the professional services sector.
  • Small Business ERPs: Aimed at businesses with fewer operations, cloud-based ERPs like Oracle Netsuite, Sage, and Acumatica offer lightweight solutions that are affordable and scalable. These are suitable for small businesses seeking cost-effective and easily manageable systems.
  • Midsize Business ERPs: Organizations that have outgrown disparate programs often turn to connected systems for automation and visibility. Microsoft Dynamics 365 Business Central, Oracle JD Edwards, and Oracle NetSuite are preferred choices for midsize companies, offering automation and visibility without extensive customization needs.
  • Enterprise ERPs: Large corporations opt for on-premises or hybrid ERPs to retain control and connectivity across departments. SAP S/4HANA and Oracle ERP Cloud are common choices, providing extensive modules, tools, and features for complex organizational needs.

There have been significant transformations in ERP solutions, driven by simplified deployment, cost-effectiveness, and heightened flexibility, particularly in facilitating remote work scenarios. The Two-Tier ERP strategy has gained popularity because it allows companies to maintain a core ERP system at the corporate level while subsidiaries leverage a different ERP solution, often cloud-based, fostering cost-efficiency and adaptability to specialized needs. ERP systems are evolving into comprehensive hubs, integrating with emerging technologies like the Internet of Things (IoT) and artificial intelligence (AI), streamlining core processes, and offering deeper insights into customer behavior. Moreover, the trend toward personalization in customer experiences is driving the adoption of low-code platforms, allowing businesses to tailor ERP systems to specific needs. ERPs are also now being augmented with AI-powered insights and enhancements with the use ofmachine learning capabilities to deliver personalized insights and optimize various business processes.
